Rear Air bags
The issue of rear side air bags as I understand it is not absolutely a size and weight issue. The issue is if they fall asleep in the back with their heads resting on the side panel and the bags should deploy. They make you sign a waiver in order to activate them because they are not meant to deploy into a kid's head. It is meant to deploy at shoulder height or below. I ordererd them for my car and this whole area was never explained to me and BMW obviously feels that they are best used by adults but never informed me of this and I wasted my money because I have young kids and it is questionable whether I will activate them before I sell my car.
